1H-Indole-3-acetic acid 87-51-4 plant growth regulator

1H-Indole-3-acetic acid CAS: 87-51-4 is made with 1H-indole, formaldehyde and potassium cyanide as raw materials through 2 steps conversions. 1H-Indole-3-acetic acid CAS: 87-51-4 is an auxin. The natural auxin that is ubiquitous in plants is indole acetic acid. 1H-Indole-3-acetic acid promotes the formation of the top bud end of plant shoots or shoots, shoots, and the like. Its precursor is tryptophan. Indoleacetic acid is the physiological effect of auxin, which is related to its concentrations. At low concentrations, growth can be promoted, and at high concentrations, and at high concentrations, growth is inhibited even plants are killed. This inhibition is related to the ability to induce ethylene formation. 1H-Indole-3-acetic acid CAS: 87-51-4 is an N-containing, organic heterocyclic chemical as colorless crystal powder. It would be became rosy powder.
